Trojský kůň „vydírá" uživatele

Trojský kůň detekovaný jako Trojan.MBRLock přepíše MBR počítače a při spuštění je uživateli oznámeno, že všechna data na jeho disku jsou zašifrovaná. Pro znovuzískání dat má uživatel zaplatit, poté mu bude údajně sděleno heslo k dešifrování. Více podrobností uvedl Marco Giulian ve svém článku, kde rozebírá i možnosti záchrany dat.

Zpravicka o windows aneb kazdy widle user je adminem.

[Peter H.]

This action is available only to users with administrative privileges, and in Windows Vista/7 it needs to pass through the User Account Control.

Čo dodať.

[Jardík]

it needs to pass through the User Account Control

Na UAC bacha, pokud ho nenastavíte na max level a necháte ho na výchozí hodnotě, pak je naprosto k ničemu a tak ho může s minimem snažení obejít každá šmejďárna.

[luta]

ja radeji nez UAC mlatim admin heslo pokazde, kdyz chci neco zmenit :D

[Jardík]

Však pokud uživatel není v admin skupině, tak UAC po něm heslo chce ...

[flexo]

Jo, a to se mi kolegové takyadministátoři smějí, že mám silné heslo a uživatelský účet obyčejný user. A když něco stahuju z internetu a instaluju/spouštím, tak si ověřuju odkud to pochází, a občas to raději ani nespustím. O crackování a stahování nelegální verzí sw nemluvě. A když jsem volal do české pošty, aby mi sdělili otisk a další náležitosti kořenového certifikátu autority, tak se na mě dívali jak puci, co prej to dělám za blbost, vždyť je to uvedený na stránkách postsigna. Asi nastal čas oprášit ettercap a sslstrip a dát jim všem najevo, že by si měli doplnit vzdělání.

[heh]

ještě že používám GPT

Onehalf se vratil.

[Mti.]

Ne, ten alespon skutecne neco delal. :-/

[Grunt]

Jo, je to podobný virus jako instalátor systému Windows, aspoň teda od pohledu. Stačí na něj antivirus s názvem grub-install?

[Johny z Podoli]

no, podle toho co se píše v článku nestačí, protože modifikuje i partion table... ale jinak souhlas :D

[Grunt]

To zas je specialita viru jménem Mironet. Na ten stačí antivirus jménem PartedMagic s modulem TestDisk.

[Tomáš]

Aspoň se ukáže, kdo poctivě zálohuje. Včetně partition table a MBR.

[bohyn]

Only wimps use tape backup: real men just upload their important stuff on ftp, and let the rest of the world mirror it ;)
-- Linus Torvalds

[Grunt]

Co může být na 512b místa tak důležitého že by to stálo za zálohu?

[Jiří J.]

... když se to navíc dá vygenerovat znovu

[pc2005]

Kdyby 512 bajtů . U jedný partišny jsou to jen dvě 32bit čísla .

[Filip Jirsák]

Rozdíl v tom je. Instalátor Windows chce zaplatit předem

[jiri.one]

+1 :)

[xkucf03]

[Mti.]

muehehehe

[gtz]

:) někdo modifikoval OneHalfa :)
